A large clean-up operation is underway in Texas after an oil spill in Galveston Bay. Over 168,000 gallons have spilled since Saturday from a barge that collided with a ship. Coast Guard Captain Brian Penoyer said the oil spill threatens to move offshore.

Brian Penoyer: “The collision itself did release a significant amount of oil, and that quantity of oil is not only in the Galveston Bay, but now, as the winds and the tides drive it out, proceeding out and offshore.”

The ship was carrying thick marine shipping oil. The spill falls along a route flown by birds as part of their seasonal migration.
